COOKING-STOVE.

' SPECIFICATION forming part of Letters Patent No. 277,009, dated May 81883.

Application filed October 30,1882. (No model.)

- To all whom it may concern:

Be it known that we,NEwToN COOPER and THOMAS ERSKIN OoNwELL, citizens ofthe United States, residing respectively at Maysville, in the county ofMason and State of Kentucky, and Aberdeen, in the county of Brown andState of Ohio,have invented certain and useful Improvements in (looking,

Stoves; and we do hereby declarethat the foL 1o lowing is a descriptionthereof. 1 Our invention relates to thatzclass oficooking-stoves inwhich aliningof cast-ironorfirebrick is usedto protect the stove frombeing burned out, and upon which a vessel of water is permanently kept;and it has for its object to provide means whereby the top and lining ofthe stove may be prevented from warping by unequal heating or by suddenand local cooling, and whereby a reservoirof water may be constantlykept hot for use.

struction and combination of parts forming the top and lining of astove, and a water-reservoir, hereinafter fully described and set 1 2 5forth, .reierence being had to the accompany- A represents the top of acast-iron stove,

provided with a water-passage (shown by the heavy dot-ted line i tj,Fig. 1, and in section at i, Fig. 2) formedpn its under side by laying acore in I the' molding-sand, as usual for such purposes, and casting thewater-passage 0 extends all around the inside opening of the stovewherethe top is exposed to the greatest heat, and is intended to-be suppliedwith water to absorb and distribute the heat, thereby preventing thestove from being warped in that locality. V

I is a shortelbow of common iron pipe, fitted into the stove-top in theusual way to meet passage 2 and connect the samewith the water-reservoirG, into the side of which itenters 5o nearthe bottom to receive water.therefrom tov be circulated around the stove-top in passage '5.

.. To this end our invention oonsistsin the contrying to save it fromwarping. As water exin the body of the stove-top. This passage ervoir Gto discharge the water heated in {ms 5 sage a into the reservoir, thatthe water may be exposed to the air to keep it cool enough to remainliquid rather than to pass otl' as steam,

which it would do if not kept in circulation.

represents the cross-piece of the stovetop between the holes, usuallycast separate from the main top. We provide this portion with thes'amestyle of water-passage, e h.

E is the discharge-pipe, connecting with the end 6. I 6 5- H is theinlet, connecting with the-reservoir like pipe 1, but further providedwith a pipeunion, a, which may be unscrewed when it is desired to removethe part 0 from the stove, both pipes E H being permanently secured 7pthereto. The water enters pipe H, passes along it to h, across to e, andback by c and E into the reservoir. l

If desirable, the front cross-piece, B, may also be furnished with apassage forwater; 5. but as this piece is often removed from the stovein common use, it may not be worth while to sacrifice convenience toeconomy in pands into steam under normal pressure at' a heat of 212Fahrenheit, and as iron does not become red hot under 875 of heat, itwill be seen that so long as water is kept in these passages the stovecannot be overheated in that locality. -At the same time the water willbe 8 5 heated and may be used from the reservoir for any purpose. Thereshouldalways be enough water kept in the reservoir to cover bothinlet-pipes.

The reservoir should not be so near the pipe F of the stove or anyheat-flue as to be heated thereby, as it is not desirable to have thewater heated by other means than the pipes described.

b is a faucet for drawing water from the res- 5 glazed internally toprevent their absorbing water and then being burst to pieces by theformation of steam in their pores when heated.

The lining-pieces K may be connected with the reservoir G by other pipesthan those cast integral with the stove-top by passing said pipesthrough suitable openings in thestove 7 near the reservoir and thenceforward to the lining. In this case one pipe will communicate with thereservoir above and the other below the water-level, as described ofpipes J and I.

We are aware that water-pipeslhave been placed contiguous to the undersides of stovetops and to the rear sides of stove fire-backs,

but not entering the body of either, and we do notclaim the same. In ourinvention the water enters directly into the body of both the passagesij cast therein, in combination water therefrom, and the other end of thepassage communicating with the top of the reservoir by a pipe connectedwith or contiguous to the reservoir to returnwater' into it, as shownand described.

2. The stove-top A, having the passage or with the reservoir G and pipesI and J, communicatin g therewith, as shown and described.

3. The stove-top A, the reservoir G, and the cross-piece 0, havingpassages h h e 6 therein, in combination with the-inlet-pipe H, providedwith the union a, and the pipe E, both communicating with the reservoir,as shown and described.

4. A range or stove back made hollow, in combination with a stove-tophaving waterpassages formed therein, and pipes connectingthe interior ofsaid hollow back with said water-passages, as shown and described.

In testimony whereof we affix our signatures in presence of twowitnesses.
